As a product owner, I should be able to to copy any feature of which I am a reviewer into any product that I am product owner or contributor on. I may want to reuse majority of the feature for my product, and make slight tweaks without needing to rewrite it (especially if there are a lot of requirements and todos).
I imagine it would go something like this
1. As Reviewer of Project A, select a feature
2. Go to ACTIONS > COPY > to a Product B that I own. I would not be allowed to select MOVE or any other actions.
